Top ball machines — where a ball drops through a series of pegs before landing in a numbered slot — are one of the most popular redemption games in arcades worldwide. They are also one of the most heavily targeted by result-leak cheating. The physical ball drop is visible, which creates the same false sense of security as ball-roulette machines. But like ball-roulette, the cheating happens at the sensor level, not the visible drop level.
I have investigated 25 top ball machine cheating incidents across venues in the UK, US, and Asia. In 22 of those cases, the cheating method targeted the sensor that detects the ball’s final position. The cheater either intercepted the sensor signal to predict the result, or injected a false signal to trigger a payout without a winning ball drop.
How Top Ball Result Leaks Work
When the ball lands in a slot, it triggers a microswitch or optical sensor at the bottom of that slot. The sensor sends a signal to the main board indicating which slot received the ball. This signal travels along a wiring harness from the sensor array to the board. A cheater who taps into this wiring harness can either read the signal — knowing the result before it is displayed — or inject a false signal from a different slot, causing a false payout.
The second method is the wireless RF leak. The sensor signal, as it travels through the wiring harness, generates RF emissions that carry information about which slot was activated. A cheater with an RF receiver positioned near the machine can capture these emissions and decode the result.
How the V5 Anti-Theft Dog Stops Result Leaks
The V5 anti-theft dog is specifically designed for top ball machine protection. It monitors the sensor wiring harness for any attempt to tap into the signal line. When it detects a tap device — either wired or wireless — it blocks the signal from being transmitted outside the protected zone. The V5 also monitors the frequency band for RF leakage and blocks the emissions at the source.
The V5 covers a 5-8 meter range per installation, making it suitable for protecting individual top ball machines or small clusters. Installation takes under 30 minutes and requires no modification to the sensor array or the main board.
If your top ball machine is showing signs of result-leak cheating or players consistently winning above the expected rate, send me a message with your machine model and a photo of your setup. I will do a quick remote check for free. Every device comes with a money-back guarantee, official invoice, express shipping, and 1-on-1 technical support.

Frequently Asked Questions
Q: How can I tell if my top ball machine has a sensor tap device?
A: Physically inspect the sensor wiring harness. Look for any small module attached to the wiring. Also check for RF leakage using a spectrum analyzer.
Q: Does the V5 device require calibration for different top ball machine models?
A: No. The device works on all top ball machine models. It monitors signal characteristics that are common across all manufacturers.
Q: Can the V5 device also detect cheating through the ball drop mechanism itself?
A: The V5 focuses on electronic signal interception. Physical manipulation of the ball drop — such as using a magnet to influence the ball’s path — requires a different countermeasure.
Q: Will the V5 device interfere with the machine’s normal payout operation?
A: No. The device only blocks unauthorized access to the sensor signal. Normal sensor readings are passed through without interruption.
